What is the significance of using array_values() in PHP when dealing with arrays?

When dealing with arrays in PHP, the array_values() function is significant because it reindexes the array numerically, starting from index 0. This can be useful when you want to reset the keys of an array to consecutive integers, especially after manipulating the array by adding or removing elements. 

// Example of using array_values() to reindex an array
$myArray = array("a" => "apple", "b" => "banana", "c" => "cherry");

// Reindex the array numerically
$reindexedArray = array_values($myArray);

// Output the reindexed array
print_r($reindexedArray);
